Quality product

The frame rails are well constructed and fit as described. I have not had the opportunity to drive the car with the rails installed as yet,

Installed on a rx7 fc

Fits okay on a FC, pretty straight forward install. Definitely not made to fc rail dimensions. Metals not quite thick enough to warrant using a jack in the middle of the railbut that was expected. im more then happy with the quality of the package and product. It was a fun time hammering my bent up floors to bolt in the reinforcements!

Good quality for the price

They look awesome, the fit is nice and snug on the stock frame rails. My only complaint is the holes for the fuel line brackets did not line up at all so I have to drill new holes to use the bolt holes for the fuel line brackets. Other than that, frame rails are great.

Great product

Installation was a breeze and quality is great

Frame rails.

Appears to be good quality. Looking forward to getting them installed and tightening up my little black bean!
